A predictive dialer is an outbound calling system that automatically dials from a list of telephone numbers. Like other types of autodialers (also called robodialers), predictive dialers call numbers automatically and can help agents screen for busy signals, voicemail, no-answers and disconnected numbers.

So what sets predictive dialers apart from other automatic dialers? Their ability to utilize call metrics to predict the moment when human agents will be available to make the next call. Another distinguishing feature of predictive dialers is that they dial multiple numbers at the same time. The goal is to call the right number of leads at the right time to ensure maximum agent utilization.
